Microsoft 365 & Email Security

A stolen password by itself should open nothing. Every sign-in gets checked twice, and nobody can forge an email that looks like it came from your Orlando business. Moving to Microsoft 365 from something else, or consolidating tenants? That's covered here too.

Where most breaches start

Email is still the front door. Infiniti locks it at the DNS level.

Phishing and business email compromise remain the most common way firms get breached. Two layers stop most of it: multi-factor authentication on every sign-in, and DNS-level email authentication that prevents anyone from spoofing your domain.

This isn't a one-time setting. Conditional access policies, legacy authentication, and audit logging all need to be configured correctly and kept that way as Microsoft changes its platform, part of the ongoing oversight covered by Fractional IT Director and paired with the broader protections on the Cybersecurity page.

What's included

  • Multi-factor authentication (MFA) on every account
  • Conditional access policies
  • Legacy authentication disabled
  • Audit logging enabled
  • SPF, DKIM & DMARC configured at the DNS level
  • DNS record hardening
Full breakdown

Everything covered in Microsoft 365 & email hardening

Multi-Factor Authentication

Required on every account, from leadership to staff, with no standing exceptions.

All accountsConditional accessRisk-based promptsNo exceptions

Email Authentication

SPF, DKIM, and DMARC configured so nothing forges a message that looks like it's from your domain.

Identity & Access Management

Azure AD hardened, legacy authentication disabled, sign-ins monitored for anomalies.

Advanced Microsoft 365 & Teams Management

Beyond basic setup, Teams, SharePoint, and cloud applications administered as part of the environment, not left to default settings.

Cloud Infrastructure & Governance

Multi-cloud administration so growth doesn't outpace what's actually being managed.

Vendor & License Management

An honest look at what you're paying for versus what's actually in use, handled as part of ongoing vendor management.

Also migrating?

Moving into Microsoft 365, or consolidating what's already there

Whether it's leaving a legacy email host, merging tenants after an acquisition, or standing up SharePoint the right way from day one, migrations get the same hardening covered above applied from the start, not bolted on afterward.

Assessment & Migration Planning

A structured review of mailboxes, files, and permissions before anything moves, so nothing gets discovered mid-migration.

Migration & Configuration

Phased cutover that preserves folder structure, permissions, and mail flow, scheduled to avoid disrupting the business.

Validation & Enablement

Post-migration checks confirm nothing's missing, then the team gets trained on what changed.

The three-letter layer

SPF, DKIM & DMARC, in plain terms

SPF

Tells the internet which mail servers are allowed to send email for your domain, anything else gets flagged.

DKIM

Digitally signs outgoing mail so receiving servers can verify it wasn't altered in transit.

DMARC

Tells receiving servers what to do with mail that fails SPF or DKIM, and gives you visibility into who's trying to spoof your domain.

Getting hardened

How the hardening process works

01

Audit the Tenant

Review current MFA coverage, conditional access, legacy auth status, and existing DNS records.

02

Harden Identity

Enforce MFA firm-wide, disable legacy authentication, and configure conditional access policies.

03

Configure Email Auth

Set SPF and DKIM, then move DMARC from monitoring to enforcement in a controlled rollout.

04

Monitor & Alert

Sign-in anomalies and DMARC reports are reviewed on an ongoing basis, not set-and-forgotten.

Common questions

Modern MFA (push notifications, biometrics) adds seconds, not minutes, and conditional access can reduce prompts on trusted devices and networks.
Usually not fully. Microsoft 365 ships with security features off or loosely configured by default; hardening it correctly takes deliberate setup, which is exactly what this service covers.
SPF, DKIM, and DMARC apply at the DNS level regardless of email platform. Talk to Dave about your specific setup during a strategy call.
Rolling out DMARC from monitoring to enforcement is done gradually and reviewed against reporting data specifically to avoid blocking legitimate mail.
Yes. Assessment, the phased migration itself, and post-migration validation and training are all part of this service, hardening is applied from day one rather than added after the fact.
